Field Function
CKLOL 0= SI5341 clock synthesize locked.
1= SI5341 clock synthesize has lost lock on outputs.
0
RT25G
Retimer 25G PHY Loss of Lock:
0= Retimer has lock on all lanes.
1= Retimer has lost lock on one or more lanes.
Note: Since the 25G retimer services a pair of independent lanes, the global lock reporting is less useful.
3.23 Watchdog (WATCH)
Address
Register Offset
WATCH 01Fh
Function
The WATCH register selects the watchdog timer value used during the reconfiguration processes. When RCFG[WDEN] enables
the watchdog timer, a count down timer begins. If the DUT software does not disable or restart the watchdog timer within the
specified limits, the system restarts.
Note that the watchdog timer is not dependent upon a reconfiguration sequence being active. While it is typically enabled along
with RCFG[GO] as part of a reconfiguration sequence; in fact, it is independent and can be enabled for any reason.
